Answers From the Lab. Several major medical organizations recommend routine screening for unhealthy alcohol use. This blood test has a much longer window of detection than existing urine tests for alcohol use. Jannetto says. The preferred screening approach for ethanol — the chemical term for alcohol — measures certain substances that the body produces when ethanol is metabolized. The direct ethanol metabolites i. The window can be longer in individuals who chronically or excessively consume alcohol," Dr.

Peth

Phosphatidylethanols PEth are a group of phospholipids formed only in the presence of ethanol via the action of phospholipase D PLD. Chemically, phosphatidylethanols are phospholipids carrying two fatty acid chains , which are variable in structure, and one phosphate ethyl ester. When ethanol is present, PLD substitutes ethanol for water and covalently attaching the alcohol as the head group of the phospholipid; hence the name phosphatidylethanol. Normally PLD incorporates water to generate phosphatidic acid PA ; the process is termed transphosphatidylation. The lipid accumulates in the human body and competes at agonists sites of lipid-gated ion channels contributing to alcohol intoxication. Levels of phosphatidylethanols in blood are used as markers of previous alcohol consumption. However, it has been demonstrated that there can be significant inter-personal variation, leading to potential misclassification between moderate and heavy drinkers. The Society of PEth Research [9] published a harmonization document Consensus of Basel for the interpretation of phosphatidylethanol concentrations in the clinical and forensic setting.

In most studies, the alcohol marker phosphatidylethanol PEth was used to differentiate social drinking from alcohol abuse. This study investigates PEth's potential in abstinence monitoring by performing a drinking study to assess the detection window of PEth after ingesting a defined amount of alcohol. In the week after drinking, blood and urine samples were taken daily; in the second week, samples were taken every other day. Ethyl glucuronide and ethyl sulfate were determined in urine for abstinence monitoring. Positive PEth values resulted from drinking events prior to this abstinence period. After the start of drinking, maximum BACs were reached after 2 h with a mean of 0. After this event, PEth was detectable for 3 to 12 days with a mean half-life time of approximately 3 days.
